Analysis of published research papers based on experimental data from Luancheng Agro-Ecosystem Experimental Station of Chinese Academy of Sciences

Bibliometeric analysis tools combined with CNKI and ISI Web of Knowledge literature databases were used to identify published research papers on experimental data from the Luancheng Agro-Ecosystem Experimental Station of Chinese Academy of Sciences for 1981~2010. The search and analysis yielded 1 151 published papers, of which 920 were in Chinese and 231 in English. For 1981~2010, the number of published papers increased with time. Prior to 2001, papers were mainly published in Chinese. The number of papers published in English increased at an annual rate of 22.4% after 2001. Number of papers published in Chinese peaked in 2005. The authors' institutions were mainly in Hebei Province, Beijing City and Shandong Province. Most of the international coauthors were in Japan and the United States. Wheat, maize, water use efficiency, yield and soil moisture were the most frequent key words, indicating that water use by wheat and maize was the most commonly research fields at the station. The published papers were largely funded by the National Science and Technology Programs and Chinese Academy of Sciences Programs. Some of the papers were, however, funded by the Science and Technology Programs of the local governments. A relatively small number of the papers were funded by international cooperations. The publishing journals mainly included the Chinese Journal of Eco-Agriculture; Agricultural Research in Arid Areas; Acta Agriculturae Boreali-Sinica; Hydrological Processes; Agricultural Water Management; Plant, Soil and Environment; and Irrigation Science. On the average, each of the published papers was cited 5.6 times for 1981~2010. A total of 6 papers were cited more than 100 times and 34 papers cited more than 50 times.
